From a7fdd90bc43e3e9cb08bc1b13650024d419b89e5 Mon Sep 17 00:00:00 2001 From: Paul Mackerras Date: Sun, 15 Jan 2006 17:30:44 +1100 Subject: [PATCH] ppc: Remove powermac support from ARCH=ppc This makes it possible to build kernels for PReP and/or CHRP with ARCH=ppc by removing the (non-building) powermac support. It's now also possible to select PReP and CHRP independently. Powermac users should now build with ARCH=powerpc instead of ARCH=ppc. (This does mean that it is no longer possible to build a 32-bit kernel for a G5.)
